The present invention relates to a dust disk collecting mechanism that sucks and removes residual powder.

Rotation-distribution-type powder medicine packaging machines (see, for example, Patent Documents 1 and 2) receive powder medicines that are supplied in small quantities or in small quantities one after another while rotating powder medicine supplied from this powder feeder. The rotary annular receiving member that holds the powder evenly distributed in the powder receiving part by means of, and the powder that is divided and discharged from the powder receiving part of this rotary annular receiving member one by one with a wrapping paper etc. And a packaging device for packaging.
As the rotary annular receiving member, there are a plurality of compartments, that is, a powder divider in which divided mass bodies are arranged in an annular shape, a turntable having an annular flat mounting surface, and a concave arc-shaped groove called an R groove. A turntable having an annular annular tray is used.

  In such a conventional dusting disk dust collection mechanism, the dust collection head can be raised and lowered, and during powder distribution division, the dust collection head is lifted away from the rotary annular receiving member until it does not suck the distribution powder, and residual powder cleaning is performed. At times, the dust collecting head is lowered to a position where it comes in light contact with the rotary annular receiving member. If such a movable dust collection head is equipped with an additional open / close valve for a movable member, the structure becomes complicated and the sucked powder tends to adhere and clog in the mechanism, so that the dust collection disk dust collection mechanism is cleaned. Because the load of maintenance work is increased, there is no on-off valve that executes / stops the intake air from the dust collection head by switching the open / close state. Instead, the dust collection head is raised and lowered while continuing the intake from the dust collection head. To stop / execute residual powder cleaning.

However, continuing to inhale even during non-cleaning, which takes longer than when cleaning residual powder, will lead to wasteful use of negative pressure suction, and there is a demand to limit the intake from the dust collection head to cleaning residual powder. It is growing. In particular, in a so-called double disk powder dispenser equipped with a plurality of sets of rotary annular receiving members and powder feeders, a dust collection head is provided for each group, but the dust collection hose and dust collector body are shared. In many cases, the suction of the residual powder is stopped farther from the rotary annular receiving member than the dust collecting head that sucks the residual powder by approaching or contacting the rotary annular receiving member. Since the dust collection head has a smaller suction resistance and a larger amount of intake air, waste of negative pressure suction is easily noticeable if the intake air is kept constantly.
Therefore, the above-mentioned on-off valve is introduced to reduce the negative pressure suction waste, and even if the on-off valve is introduced, the burden of cleaning and maintenance work associated with it can be reduced, and the structure can be kept relatively simple. Realizing a disk dust collection mechanism is a technical issue.

  The powder disk dust collecting mechanism of the present invention (Solution means 1) was devised to solve such problems, and a suction port is provided in the powder receiving part of a rotary annular receiving member that is mounted together with the powder packing machine. A dust collection head having a suitable shape, a head support portion that holds the dust collection head so as to be movable up and down, and is formed with an intake path that leads to the suction port of the dust collection head, and the head support portion. A dusting disk dust collection mechanism equipped with a head drive unit that is mounted and drives the dust collection head to move up and down, and is a manual operation member equipped on the head support unit, the dust collection head being attached to the head support unit A latching member that is detachable, an opening / closing valve that is provided inside the attachment / detachment part of the dust collecting head on the surface of the head support part, and that is provided on the head support part. Opening the on-off valve Characterized by providing a valve driving unit for driving.

  Further, the powdered disk dust collecting mechanism of the present invention is (the solution means 2), the powdered disk dust collection mechanism of the solution means 1, wherein the head driving unit is moved by a driving source, the driving source, and this A head driving force transmission cam mechanism including a follower for transmitting the movement to the dust collecting head, and the valve driving unit moves the movement by the driving source and the movement to the opening / closing valve. A valve drive force transmission cam mechanism comprising a follower that transmits to the valve is provided.

In such a powdered disc dust collecting mechanism of the present invention (Solution 1), the dust collecting head can be easily detached from the head supporting portion by manually operating the latching member provided on the head supporting portion. As a result, the dust collecting head can be easily and sufficiently washed by round washing or the like, and thus the powder adhering to the dust collecting head can be securely dropped.
In addition, since the opening / closing valve and the valve drive unit are mounted on the head support part so that the intake path therefor is opened and closed, intake air can be limited when dust collection is necessary, so that the negative pressure suction waste is reduced. . In addition, by removing the dust collecting head after the intake passage is closed by the on-off valve, it is possible to prevent powder powder from returning from the intake passage easily and reliably.

In addition, since the on / off valve is located on the inside of the dust collection head attachment / detachment part on the surface of the head support part, the on / off valve is exposed when the dust collection head is removed. Cleaning such as work can be easily performed.
In addition to such cleaning, maintenance work such as repair and replacement can be easily performed for both the dust collection head and the on-off valve.
Therefore, according to the present invention, it is possible to realize a dusting disk dust collecting mechanism that can reduce the burden of cleaning and maintenance work even if an on-off valve that can reduce waste of negative pressure suction is introduced.

Further, in the powdered disk dust collecting mechanism of the present invention (Solution means 2), the head driving unit and the valve driving unit share one driving source, and the driving force transmission mechanism can be integrated into the original section. By adopting a simple cam mechanism, the valve drive part added with the additional introduction of the on-off valve is the original part of the valve drive force transmission cam mechanism in addition to the follower and support part of the valve drive force transmission cam mechanism. A small one is sufficient.
Therefore, according to the present invention, even if an on-off valve capable of reducing the waste of negative pressure suction is introduced, the burden of cleaning and maintenance work related thereto can be reduced and the structure of the powdered disc can be kept relatively simple. Can be realized.
